The main character ( the one with white hair) is the 2nd prince of the dragon clan which inherits the powers of the water dragon. So he doesn’t inherit the powers for some reason and set himself to go on a journey, which he encounters the black dragon. The black dragon is a dragon that is in love with the main character and tries everything he can with the main character but not everything works. As for the main character’s guardian, he is “earth” Which he has had a past relationship with the main characters older brother. That encounter wasn’t very good in the least which ended up with him being raped and the older brother losing his memories/ not being able to recall the memories.
